Hello there! Hope you are having a good day! I'm not in the best of moods today. It's that time of month for me, if you know what I mean. It's not always fun being a woman. Anyways, today's thingamajig is becoming obsolete because of the technology that is available today. They were quite popular in the 80s and 90s. It's made of plastic and is portable. Japan and the United States are two major manufacturers. What is it?
